Sergei is a pianist and he is Jewish, just like Lou. Nevertheless, their daughter Rosa has never been to a synagogue - completely normal for a Jewish family in Berlin. But what is a family anyway? In search of an answer, Lou accepts an invitation to her aunt's 90th birthday party, meets the entire ex-Soviet clan from Israel on Gran Canaria before realising that she will have to look for the answers to her multi-layered identity in Tel Aviv. A highly topical family novel.
